DotnetopenAuth引发" ProtocolException [英] DotnetopenAuth throws a "ProtocolException

问题描述

我正在尝试使用ASP.NET MVC实现OpeinID登录。我正在尝试按照 http://blog.nerdbank.net/2008/04/add-openid-login-support-to-your-aspnet.html

I am trying to implement OpeinID login with ASP.NET MVC. I am trying to follow steps given as in http://blog.nerdbank.net/2008/04/add-openid-login-support-to-your-aspnet.html

下面是我的设置web.config

Below is my settings web.config

<dotNetOpenAuth>
<messaging>
    <untrustedWebRequest>
        <whitelistHosts>
            <add name="localhost" />
        </whitelistHosts>
    </untrustedWebRequest>
</messaging>
<reporting enabled="false" />

<system.net>
<defaultProxy useDefaultCredentials="true">
    <proxy autoDetect="True" usesystemdefault="True"/>
</defaultProxy>

我得到了'ProtocolException'尝试创建请求时说找不到openId端点。

I get the 'ProtocolException' saying 'No openId end point found' when I try to create a request.

try 
{
    //ProtocolException is thrown
    IAuthenticationRequest request = openID.CreateRequest(openid_identifier); 
    request.RedirectToProvider();
}
catch (ProtocolException )
{
    throw;
}

Dotnetopenauth生成的日志文件。 （我已经用< myopenid> 替换了我的有效用户ID）

Log File generated by Dotnetopenauth. (I have replaced my valid userid with <myopenid> )

   at DotNetOpenAuth.OpenId.RelyingParty.AuthenticationRequest.Create(Identifier userSuppliedIdentifier, OpenIdRelyingParty relyingParty, Realm realm, Uri returnToUrl, Boolean createNewAssociationsAsNeeded)

然后我与提琴手进行了检查，发现没有生成任何请求来获取URI。似乎dotnetopenauth无法生成请求，并且在那里失败。

I then checked with fiddler and I see no request getting generated to get the URI. It seems that dotnetopenauth is not able to generate the request and is failing there.

有人可以在这里帮助我吗？我缺少什么吗？

Can anybody please help me out here? Anything that I am missing?

我正在从代理后面工作。

I am working from behind a proxy.

推荐答案

我只建议您编写一个简单的C＃控制台应用程序，该应用程序使用 HttpWebRequest 从要输入DotNetOpenAuth的OpenID URL下载页面，因此您可以自己查看故障，并诊断防火墙/代理设置有什么问题。

All I can suggest is that you write a trivial C# console app that uses HttpWebRequest to download the page from your OpenID URL that you're typing into DotNetOpenAuth so you can see the failure yourself, and diagnose what's wrong with your firewall/proxy settings.
